PROBLEM TO BE SOLVED: To reduce powder leakage during powder charging.SOLUTION: A powder feeding device 10 for a powder molding machine comprises a leveling plate 11 which slides on a molding metal mold table 30 and can feed powder through a power feed port which is provided on a sliding surface thereof, and a rotation mechanism 15 which rotates the leveling plate 11 with a shaft perpendicular to the molding metal mold table 30. The leveling plate 11 has a recess region 19 provided with at least one recess 18 and a planar region 20 having no recess with the powder feed port interposed therebetween on the surface sliding on the molding metal mold table 30. The rotation mechanism 15 is so rotated that the recess region 19 is located at a rear position with respect to a travel direction of the leveling plate 11, thereby preventing powder from entering the recess 18 from the travel direction.SELECTED DRAWING: Figure 1 |
